Application filed October 3, 1910. Serial No. 585,075.

To all whom it may concern:

Be it known that I, NEWTON A. SMITH, a citizen of the United States residing at Marion, in the county of Williamson and State of Illinois, have invented a new and useful Coal-Washer of which the following is a specification.

This invention relates to coal washers and it consists in the novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to provide in a coal washing apparatus a jig resiliently mounted for reciprocatory movement and a valved chamber also mounted for reciprocatory movement and adapted to cooperate with the jig in such manner that the finer particles of coal will not be drawn down through the bottom of the jig as the same moves in an upward direction. The jig and the said valved chamber are mounted in a water tank and the jig is provided with suitable gates or valves through which the refuse and other foreign bodies may be permitted to pass from the jig at the desired intervals.

In the accompanying drawings;Figure 1 is a side elevation of the coal washer with parts broken away, and parts in section. Fig. 2 is a transverse sectional view of pertions of the coal washer. Fig. 8 is a detail sectional view of a portion of the coal washer.

The coal washer comprises a tank 1 into which a coal delivery chute 2 projects at its discharge end. Guide studs 3 are mounted upon the bottom of the tank 1 and a chamber a is provided at its corners with eyes 5 which slidably receive the said guide studs 3. Coiled springs 6 surround the lower portions of the guide studs 3 and are interposed between thebottom of the tank 1 and the lower surfaces of the eyes 5 carried at the corners of the chamber 4. The chamber 4 is provided at its sides and in the vicinity of its bottom with hinged gate valves 7 which are adapted to swing inwardly to open positions and which hang approximately vertical when closed. As shown in Fig. 1 of the drawings the major portions of the sides of the chamber 4: converge toward each other toward the upper end of the chamber but at the extreme upper end of the chamber the sides thereof are approximately vertical as at 8.

A jig 9 is supported (as will be explained presently) above the upper end of the chamher a and is provided at its lower side with a depending collar 10 which is telescopically received between the approximately vertical wall sections 8 of the chamber 4. The 9 is also provided with an inclined perforated bottom 11 as is usual in such structures and one end of the said jig is located under the delivery end of the said chute 2. The jig 9 is provided in its end at the lower edge of the inclined bottom 11 with an outlet opening 12 over which a gate 13 is mounted for vertical sliding movement. A lever 14 is operatively connected with the valve 13 and is adapted to raise and lower the same when the said lever is swung upon its fulcrum. A valve 15 is also pivotally mounted at the delivery end of the jig 9 and a lever 16 is operatively connected with the valve 15 and is adapted to swing the same when the said lever is moved upon its fulcrum.

The tank 1 is located upon or within a frame 16 and a driving shaft 17 is journaled for rotation at the upper portion of the said frame 16 and extends transversely across the upper end of the tank 1. Bars 18 are fixed at their lower ends to the sides of the chamber 4t and converge toward each other at their upper ends and are provided at their points of intersection with a friction roller 19. Eccentrics 2-0 are mounted upon the drive shaft 17 and the said rollers 19 bear upon the peripheries of the said eccentrics 20. Shafts 21 are also journaled for rotation at the upper portion of the frame 16 and extend parallel to the shaft 17. Gear wheels 22 are fixed to the shaft 21 and a gear wheel 23 is fixed to the shaft 17 and meshes with both of the gear wheels 22. Eccentrics 28 are fixed to the shafts 21 and are surrounded by eccentric straps 24. Blocks 25 are pivotally mounted. at the upper edges of the sides of the jig 9 and bolts 26 are slidably received in the ends of the said blocks 25 and the ends of the said bolts project some distance beyond the upper and lower sides of the said blocks. Plates 27 connect the lower ends of the bolts 26 of each pair together and coiled springs 28 are interposed between the lower surfaces of the blocks 25 and the upper surfaces of the plates 27 and surround the lower portions of the bolts 26. Plates 29 connect the upper portions of the bolts 26 together, and coiled springs 30 are interposed between the upper surfaces of the blocks and the lower surfaces of the plates 29 and surround the upper portions of the bolts 26. Rods 31 are pivotally connected at their upper ends with the opposite sides of the eccentric strap 24: and the lower edge of each rod 31 is connected to the upper edge of one of the bolts 26. By this arrangement it will be seen that the 9 is resiliently supported.

In operation the tank 1 is filled or partially filled with water and the shaft 17 is rotated. Through the said shaft 17 the shafts 21 are rotated by means of intermeshing gear wheels 22 and 23. As the eccentrics 23' are carried around the shafts 21 the rods 31 are moved longitudinally and the blocks 25 are reciprocated vertically. Inasmuch as the said blocks are pivotally connected to the sides of the jig 9, the said jig 9 is reciprocated vertically. By reason of the fact that the rods 31 are resiliently connected with the blocks 25 through the bolts 26 and coiled springs 28 and 30, the initial up and down movement of the jig 9 is cushioned and the contents of the is not subjected to whipping action. At the same time the eccentric 20 rotates about the axis of the shaft 17 and the periphery thereof operates against the roller 19 which is journaled at the upper ends of the arms 18. The chamber 1 is normally held in an uppermost position under the tension of the springs 6 which operate against the lower surfaces of the eyes 5 and consequently the said roller 19 is held against the periphery of the eccentric 20. \Vhen the deep portion of the eccentric 20 comes in contact with the said roller 19 the said roller together with the rods 18 are depressed and the chamber 1 is moved in a downward direction against the tension of the spring 6. This downward movement upon the part of the chamber t occurs when the jig 9 is moving in an upward direction and as the said jig 9 is moving in a downward direction the chamber at moves in an upward direction. At the time that the chamber at is moving in a downward direction the gate valves 7 open and permit water from the tank 1 to pass into the interior of the chamber. At the same time the jig is moving in an upward direction and during the previous descending movement of the water has passed up through the perforated bottom 11 into the material contained within the said As the jig 9 moves in an upward direction, this water is elevated and is dipped from the upper portion of the chamber Thus the water which is within the 9 is not drawn in a downward direction as the said is elevating and the chamber 1 is depending for the reason that the water which is being removed from the said chamber 4 by the jig 9 is being replaced by water flowing into the lower portion of the chamber A through the openings normally covered or closed by the gate valve 7. As the mixed material is fed into the 9 through the tube 2 and is subjected to the reciprocatory movement of the said jig while the water is passing through thesaine, the coal and lighter material will have a tendency to assume a stratum upon the slate and heavier material. This tendency is facilitated by the movement of the water through the jig 9 which volume of water is received from the chamber t in the manner as above described. \Vhen it is desired to remove the slate and other undesirable material from the 9, the lever 1 1 is swung so that the valve 15 is closed and at the same time or subsequent thereto the lever 16 is swung so that the gate valve 13 is opened. Thus the slate and other'undesir-able material which might be between the two valves is permitted to fall from the jig 9 through the opening 12. This operation upon the part of the valve 15 and gate 13 may be repeated as often as necessary to remove the slate etc.

Having described the invention what is claimed is 1. A coal washer comprising a tank, a chamber mounted for reciprocat-ory movement therein and having valved inlet openings, a mounted for reciprocatory movement in the tank and telescopically engaging the chamber, and means for reciprocating the said chamber and jig simultaneously in opposite directions.
